AUTOMOBILE-DRIVER' TIRE-PUMP.

Speecation of Letters Patent.

Patented Mar. 23, 1920.

i To ZZ whom z't may concern:

Bc it known that I, GEORGE Enom: HAZ- w, a citizen of the United States,residing :it Rochester, in the county of Monroe and Stute of New York,have invented certain new and useful Improvements in Auto mobile-DrivenTire-Pumps, ot' which the following is e specification, reference beinghad therein to the accompanying drawing.

This invention relates to improvements in automobile driven tire pumps,and it pertains to that class of tire pum s which are constructed to beattached to t e transmission case o an automobile.

My improved pump'involves e crank or eccentric case upon which `ismounted :i pump cylinder, or cylinders, and n separate gear casecarrying gears operatively connected with the pump driving shaft, the

gear case havin an open side registering with en opening in theautomobile transmisl@ion cese, whereby the gears of the pump gear caseare adapted to be driven by the gear in the automobile transmissionrase, the structure adapted to be attached in position to the saidtransmission case.

One object of my present invention is to have the gear case and thecrank, or eccentric case, separate, but so constructed that when it isattached to the gear case, it will support the other, with the gears ofthe geur rese and the drive sha-ft of the pump case in proper operativerelation with each other.

Another object of my present invention is to construct the pump gearcase so that it will carry e bearing `for an idler gear beclamping bolts5 poss und into the l.transtween the gear of the transmission case andthe gear of the pump gear case.

One of the problems of automobile driven tire pum s is,to providelubrication for the parts an at the same time prevent an excessivelubrication reaching the pump cylin` der, or cylinders, and worklng itsway to thc air compression chamber of the pump, and in that way beingforced' into the tire and rotting or deteriorating the rubber of thetire.

In the type of pump to which this invention relates, thevpump gear caseis in open commimication with the automobile traneiniesion case andreceives u large amount of lubricunt from tho tr-.nieiuieeion cose, undit is neceseury to prevent rxccseivc lubrication in the pump geur conreaching the pump crank or eccentric one(` oi bruising, and :is aconsequence, tinnlly watching the nir cono pression clnnnbor oi tin'pun-ip with ihr di etrurtive el'f-ct :there mentioned.

My present iinproicniont consiste in nniking the pump geur @use und thepump housing :separate from ouch other und having one support the otherin proper operative relution, so that the excessive lubrication in the.geur case will not reach the pump housing, und lubricution to theoperating ports in the pump housing und the cylinder is effected by aseparate nieufns constructed to be controlled to effect eiiicientlubrication, while :it the same time prevent excessive lubrication ofthe-pump parte, for the reason above mentioned.

In the nccoinpiiiiyingy druwings- Figure l is un outside elevation of npump housing and gear ense showing a part of the automobiletransmission, with the gearing shown in dotted lines.

Fig. 2 is an end elevation of my improved construction attached to theautomobile transmission euse, the gearing being shown in dotted lines.

In carrying out my presentimprovement, I provide a pump geur cuen l,which is prov vided with an open inner eide 2, that regieters with anopening in the outer .eide of the transmission raise 3 of theautomobile. "lhc opening Q of the gear ense is provided with asurrounding fiunge 4, through which mission case 3, by moons of whichthe pump geur case is 'iirmly bolted to the automobile transmissionense.

T his gear case 1 is provided with o interl) Ei :illy extending bracket6, which comprises a horizontal shelf 7, a longitudinal vertical ',rib 8extending downward from the inner 'edge of the shelf 7, and verticalribs 9, ar-

ranged transverse the Iehclf 7 en d extending to the longitudinal rib 8.f The shelf jTand the ribs 8 and 9 are inudeintegral.

A Separate pump, crank or eccentricliousing 10 is provided and the pumpcylinder, or cylinders 11, are mounted thereoiim This puin housing issupported upon and attache to the brui'lcet or sheliI 7, by suitablebolts` 12, and the bracket and heus ing are so proportioned and arrangedthat the gearshaft 13 isin pro ier operative relation, or. concentricwith tie pump operae in mechanism Within the housing lo, J

this im roved construction it will be ob served hat the housing l() andgear case 1, 0 are separate from each other, whereby the lubricant fromthe gear case will not reach the pump housing and whereby the pumphousing and the ar case are separately constructed with t e attendantadvantages in manufacture and operation of the parts when assembled Thebracket forms a solid support for the pump housing, whereby when intheir mounted ositions they avt :is a unit and both are firm y supportedin their operative positions, although they are rapa-- ble of separationas described.

Another part of my present improvement is to have the pump gearing casecarry an idler gear 13 in position to mesh with :in automobiletransmission gear 14. In the spe-V cie construction here shown, theidler gear Shaft or bearing 15 is mounted in inwardly extendingsupporting arms 16, which extend inward from the gear cese, and thisidler 3o ar 13 is movable on its shaft l5 toV bo rown in and out ofnicsli with the transmission gear 14z While remaining atA all times inmesh with a wide gear 17 of the gear case 1. A suitable shifting shiift1S extends from the outside of the gear case and carries at its innerend a suitable shifting yoke 19, for movin the idler geer'l in and outof mesh wii the transmission gear 14. 40 The primary object of this lastmentioned construction is to have, the pump gear case support an idlergear, but I do not limit myself to the specific construction here shown.Tha-t is to say, this construction 445 may be varied by len honing` thepump gear case inw ard instea of having the arms 16, and in this casethe idler gear shaft will be mounted in the gear extension; Thisnrrangement.,A of course,

gearI shaftfoutside of ie automobile transi `mission case, but it 'wiladapt the construe tion for certain forms of automobile' transmissionwhich mechanism to extend iinto the transmission case, as far as thathere shown.

y'iin either construction the idler gong is supported b the pump gearcese.

i Any suitah e means may with the shaft 18 for holding it in its tufo-Shiftcd positions-Without effecting my pres ent improvement.

I do not limit myself to the exact constiuction here shown, foraccomplishing the mounting of, separate pump gear cases sind shaft e6pump housirlgs in registered relation with will carry the idler do notrequire the pump gearhe connected enc-h other und willi wherebyi the:nlvuuiuges hel'iiubefore pointed out :ire uecomplisluul, because thecon struction here shown muy be varied without departing from myinvention, so long us tlu` objects thereof' :ire accomplished.

li? the purpose of conreuienro und brerify in the claims, the crank oreccentric case l0, will be referred to as a pump housing to distinguishit from the pump geur case 1.

Having thus described my inrentiomxvhat I claim and desire to secure byLetters Patent is'.-
